RAiLWAY CAR The present invention relates to a large volume railway car on a four-rail track for conveying bulk goods.

With a heretofore known railway vehicle which moves on four rails, the necessity exists of adapting the rail vehicle and above all the carriage or truck thereof to the track. It is particularly difficult with the heretofore known arrangement to distribute the weight of the railway car substantially uniformly onto all rails. More over, the known railway vehicle is rather expensive in construction, operation and servicing.

Another heretofore known railway vehicle movable on a four-rail track is provided with a bogie having rocker arms on its longitudinal sides which rocker arms are equipped with wheels moving on the respective outer rails of the track while the railway car body is supported by the bogie as well as by said rocker arms. The wheels mounted in said rockers have no wheel rim. The lateral guiding forces can be transferred from the wheel rim to the rail only with every fourth wheel. The high wear at the wheel and the rails inherent thereto result in high expenses. Moreover the danger of derailing due to the unfavorable ratio of the wheel pressure to the horizontal force on the wheel rims is rathere high.

It is, therefore, an object of the present invention to provide a rail vehicle for four-rail tracks which will overcome the above mentioned drawbacks and will be able to convey substantially even loads on all wheels onto the rails while making it possible to employ a track on which also vehicles with a normal gauge for instance mass produced locomotives can travel.

These and other objects and advantages of the invention will appear more clearly from the following specification in connection with the accompanying drawings, in which:

FIG. 1 is a side view of a large volume railway car according to the invention.

FIG. 2 shows the top view of a railway car according to the invention for a four-rail track according to FIG. 1.

FIG. 3 is an end view of a railway car according to the invention.

FIG. 4 illustrates on a larger scale than that of FIGS. 1 to 3 a bogie for a railway car according to the inven tion.

The above mentioned objects underlying the present invention have been realized by providing at each car end two two or more axle bogies which are interconnected by rocker arms, said bogies being arranged parallel to each other. The common bridge of said bogies carries the car body, and the wheels of the wheel sets are so connected to the axles that the wheel rims are located on the outside.

According to a further development of the invention, the rocker arms interconnecting the bogies arranged parallel to each other are designed as triangular guiding means and are elastically mounted in said bogies. Furthermore, according to the invention the spacing of the inner wheels of the bogies corresponds to the normal gauge of a railway track.

Referring now to the drawings in detail, the car body 1 rests upon the lower structure 2 which in its turn is by means of bearing sockets 3 placed upon the bridges 4 of the bogies 5. The spanner bolster or bridges 4 are pivotally mounted in bearing sockets 6 on the main transverse supports 7 of the bogies 5. These supports 7 are equipped respectively with two or more wheel sets 8 which comprise the axle 8a and. the two wheels 8b which are connected to the axle 8a-in such a way that the wheel rims or flanges 8c are located on the outside. Two adjacent bogies 5 on which the bridge 4 is pivotally mounted, are at those longitudinal sides 10 which face each other respectively connected to two groups of guiding means 12 which are located one above the other and are designed as triangular guiding means. The guiding means 12 are connected in elastic bearings 13 on the longitudinal sides 10. The guiding means 12 assure the mutual guiding and a slight displaceability of the bogies 5 which pertain to each other relative to each other. In this way, uneveness and aligning errors between the pair of rails 14 and 14a can be equalized. The distance 15 between adjacent rails 16 and 17 ofthe pair of rails 14 and 14a are so selected that normal gauge vehicles can travel on the rails 16 and 17.

Due to arranging the wheel rims or flanges 8c of the wheel sets 8 on the outside, a simple design of the switches and crossings of the four-rail track will be assured. It will also be evident from the above that the advantage of the arrangement according to the invention consists primarily in that in view of the favorable arrangement of the bogies a high stability will be realized so that the capacity of the considerably wider railway cars can be taken advantage of to its full extent.

It is, of course, to be understood that the present invention is, by no means, limited to the specific showing in the drawing but also comprises any modifications within the scope of the appended claims. Thus, instead of connecting the bogies by means of triangular guiding means, also fourcornered guiding means or guiding means arranged in pairs adjacent to each other may be employed.

What I claim is:

1. A large volume railway car in combination comprising a car body and being movable on rail tracks comprising four parallel rails, which includes two pairs of bogies, one pair of said bogies being arranged at one end of said railway car and the other pair of said bogies being arranged at the other end of said railway car, the bogies of one and the same pair of bogies being adjacent to each other, link means respectively pertaining to said pairs of bogies and respectively pivotally interconnecting the bogies of one and the same pair of bogies to each other, bridge means between said pairs of bogies, each of said bridge means being common to and pivotally interconnecting the bogies of one and the same pair of bogies while pivotally supporting said car body, each of the bogies of one and the same pair of bogies comprising a pair of independently journalled wheel sets with wheel flanges, the wheel flanges of each wheel set being arranged on those sides of the wheels of one and the same wheels set which face away from each other.

2. A railway car in combination according to claim 1, in which said link means are designed as triangular link means.

3. A railway car in combination according to claim 1, in which said link means are elastically mounted on the bogies pertaining thereto.

4. A railway car in combination according to claim 1, in which the link means pertaining to one and the same pair of bogies respectively are arranged in pairs located one above each other and substantially parallel to each other.
